2 directories, 2 files

What is this?

Searching google I only found uninformed crap.

The two files are binary data (file just says "data" and strings returns nothing useful).

If they are, as the name would imply, actually "volume settings", how can I know which volume they refer to?

I couldn't find any definitive documentation, either. The term "HFS extent tables" refers to the data organization scheme of the HFS filesystem, but I don't understand why those would exist as file data instead of metadata. What's the format of your root drive? Do you share the volume over the network? – jmk Feb 2 at 21:12
@jmk format is HFS+ journaled, and only the public folders of each user are shared. – Lohoris Feb 3 at 11:01
